Answer:

$x=\pm \sqrt{6-2y}$

$y=\frac{1}{2} (6-x^2)$

Step-by-step explanation:

$x^2+(y-1)\cdot 2 =4$

$x^2+2y-2 =4$

$x^2+2y =6$

I will solve it for $x$

$x^2 =6-2y$

$x=\pm \sqrt{6-2y}$

Solving for $y$

$y=3-\frac{x^2}{2}$

$y=\frac{1}{2} (6-x^2)$

A right triangular prism has a height of 3 ft, a width of 4 ft, and a hypotenuse of 5 ft. The depth of the triangle is missing.

DiKsa [7]

Depth=15
x=(height(h)*width(w)*hypotenuse(y))/2
x=(3*4*5)/2=(60/2)=30
y=(x(x-h)(x-w)(x-y))^(1/2)
f=(-h^4+2(hw)^2+2(wy)^2-w^4+2(hy)^2-y^4)^(1/2)
f=(-3^4+2(3*4)^2+2(4*5)^2-4^4+2(3*5)^2-5^4)^(1/2)
f=576^(1/2)
f=24
Surface Area= 2f(.5)+(h+w+y)*depth
192=depth*(3+4+5)+24(.5)
180=(3+4+5)*depth
180=(12)(depth)
15=depth
